AD648AQ

The AD648AQ is one member of the AD648 series.The AD648 is a matched pair of low power, precision monolithic operational amplifiers. It offers both low bias current (10 pA max, warmed up) and low quiescent current (400 mA max) and is fabricated with ion-implanted FET and laser wafer trimming technologies. Input bias current is guaranteed over the AD648's entire common-mode voltage range.

Features of the AD648AQ are:(1)DC Performance; (2)AC performance; (3)available in plastic mini-DIP, Cerdip, plastic SOIC and hermetic metal can packages; (4)MIL-STD-883B parts available; (5)surface mount (SOIC) Package available in tape and  reel in accordance with EIA-481A Standard; (6)single version: AD548.The AD648 is recommended for any dual supply op amp application requiring low power and excellent dc and ac performance.In applications such as battery-powered, precision instrument front ends and CMOS DAC buffers, the AD648's excellent combination of low input offset voltage and drift, low bias current and low 1/f noise reduces output errors. High common-mode rejection (86 dB, min on the "C" grade) and high open-loop gain ensures better than 12-bit linearity in high impedance, buffer applications.

The absolute maximum ratings of the AD648AQ can be summarized as:(1)supply voltage:±18 V;(2)storage temperature:-65 to +150;(3)internal power dissipation:500 mW;(4)input voltage:±18 V;(5)lead temperature range (soldering 60 sec):+300.Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection.Although the AD648 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
